Without sensors most electronic applications would not exist-sensors perform a vital function, namely providing an interface to the real world. Hall effect sensors, based on a magnetic phenomena, are one of the most commonly used sensing technologies today. In the 1970s it became possible to build Hall effect sensors on integrated circuits with onboard signal processing circuitry, vastly reducing the cost and enabling widespread practical use. One of the first major applications was in computer keyboards, replacing mechanical contacts. Hundreds of millions of these devices are now manufactured each year for use in a great variety of applications, including automobiles, computers, industrial control systems, cell phones, and many others.
The importance of these sensors, however, contrasts with the limited information available. Many recent advances in miniaturization, smart sensor configurations, and networkable sensor technology have led to design changes and a need for reliable information. Most of the technical information on Hall effect sensors is supplied by sensor manufacturers and is slanted toward a particular product line. System design and control engineers need an independent, readable source of practical design information and technical details that is not product- or manufacturer-specific and that shows how Hall effect sensors work, how to interface to them, and how to apply them in a variety of uses. This book covers:
-the physics behind Hall effect sensors
-Hall effect transducers
-transducer interfacing
-integrated Hall effect sensors and how to interface to them
-sensing techniques using Hall effect sensors
-application-specific sensorICs
-relevant development and design tools
This second edition is expanded and updated to reflect the latest advances in Hall effect devices and applications!
Information about various sensor technologies is scarce, scattered and hard to locate. Most of it is either too theoretical for working engineers, or is manufacturer literature that can't be entirely trusted. Engineers and engineering managers need a comprehensive, up-to-date, and accurate reference to use when scoping out their designs incorporating Hall effect sensors.
* A comprehensive, up-to-date reference to use when crafting all kinds of designs with Hall effect sensors
*Replaces other information about sensors that is too theoretical, too biased toward one particular manufacturer, or too difficult to locate

From the Reviews...

"This handbook will be a valuable resource for many academic libraries. Many engineering librarians who work with a variety of programs (including, but not limited to Materials Engineering) should include this work in their collection. My recommendation is to add this work to any collection that serves a campus with a materials/manufacturing/electrical/computer engineering programs and campuses with departments of physics and/or chemistry with large graduate-level enrollment."
--Randy Wallace, Department Head, Discovery Park Library, University of North Texas

With the advent of microprocessors and digital-processing technologies as catalyst, classical sensors capable of simple signal conditioning operations have evolved rapidly to take on higher and more specialized functions including validation, compensation, and classification. This new category of sensor expands the scope of incorporating intelligence into instrumentation systems, yet with such rapid changes, there has developed no universal standard for design, definition, or requirement with which to unify intelligent instrumentation. Explaining the underlying design methodologies of intelligent instrumentation, Intelligent Instrumentation: Principles and Applications provides a comprehensive and authoritative resource on the scientific foundations from which to coordinate and advance the field. Employing a textbook-like language, this book translates methodologies to more than 80 numerical examples, and provides applications in 14 case studies for a complete and working understanding of the material. Beginning with a brief introduction to the basic concepts of process, process parameters, sensors and transducers, and classification of transducers, the book describes the performance characteristics of instrumentation and measurement systems and discusses static and dynamic characteristics, various types of sensor signals, and the concepts of signal representations, various transforms, and their operations in both static and dynamic conditions. It describes smart sensors, cogent sensors, soft sensors, self-validating sensors, VLSI sensors, temperature-compensating sensors, microcontrollers and ANN-based sensors, and indirect measurement sensors. The author examines intelligent sensor signal conditioning such as calibration, linearization, and compensation, along with a wide variety of calibration and linearization techniques using circuits, analog-to-digital converters (ADCs), microcontrollers, ANNs, and software. The final chapters highlight ANN techniques for pattern classification, recognition, prognostic diagnosis, fault detection, linearization, and calibration as well as important interfacing protocols in the wireless networking platform.

This powerful tutorial is a great resource for engineers from other disciplines, technicians, analysts, investors, and other busy professionals who need to quickly acquire a solid understanding of the fast emerging and disruptive battery landscape.

The Jurgensen Dynasty represents four generations of extraordinary watchmakers working in two countries: Denmark and Switzerland. Urban Jurgensen (1776-1830) is perhaps the most renowned member of the family. He was among the most innovative personalities of the Danish Golden Age and internationally one of the most prominent watchmakers of his time. His contributions to the development of horology were significant and he was one of the first watchmakers and inventors to be recognised by the scientific establishment with his innovations in technology and science earning him a place in the Royal Danish Academy of science. In this manner, the book presents a broader cultural aspect of Danish history than the title at first suggests. It is a document of the art of watch-making, as it is still exercised by the continuing production of Urban Jurgensen & Sonner timepieces today.

Paul Newman wore his Daytona Rolex every single day for 35 years until his death in 2008. The iconic timepiece, probably the single most sought-after watch in the world, is now in the possession of his daughter Clea, who wears it every day in his memory. Franklin Roosevelt wore an elegant gold Tiffany watch, gifted to him by a friend on his birthday, to the famous Yalta Conference where he shook the hands of Joseph Stalin and Winston Churchill. JFK's Omega worn to his presidential inauguration, Ralph Lauren's watch purchased from Andy Warhol's personal collection, Sir Edmund Hillary's Rolex worn during the first-ever summit of Mt. Everest...these and many more compose the stories of the world's most coveted watches captured in A Man and His Watch. Matthew Hranek, a watch collector and NYC men's style fixture, has travelled the world conducting firsthand interviews and diving into exclusive collections to gather the never-before- told stories of 76 watches, complete with stunning original photography of every single piece.

With a foreword from Jean-Marie Schaller, founder and creative director of Louis Moinet, this book introduces some of the most elegant watches the horological world has to offer, including several one-of-a-kind pieces that have never before appeared in print. Many of these ateliers handcraft both the watches and their complicated mechanical movements in-house. The level of expertise and craftsmanship involved is truly dazzling. Featuring such stunning timepieces as the 15.48 Driver Watch, the Andreas Strehler Time Shadow and the Antoine Preziuso Chronometer, Tourbillon of Tourbillons, this expertly curated collection of watch profiles will catch the eye of any true enthusiast. Steve Huyton looks beyond the price tag, featuring affordable options of particular artistic merit as well as pieces from the luxury end of the scale. Discover the hidden gems of the watchmaking business - 60 independent artisans counted among the finest makers in the world. Includes the work of: Hajime Asaoka, Felix Baumgartner (Urwerk), Aaron Becsei, Vincent Calabrese, Konstantin Chaykin, Bernhard Lederer (BLU), Masahiro Kikuno, Vianney Halter, Antoine Preziuso and Andreas Strehler, among others.

There are names in horological history that echo much more than just watches... Such is the case of Jaquet-Droz, 18th Swiss watchmakers with an international horizon, whose ceremonial clocks, prodigious androids, fashionable birdcages, pocket watches with moving scenes or collector's snuffboxes remain the stuff of dreams for passionate enthusiasts. Today, the Maison Jaquet Droz continues to draw its inspiration from this rich heritage in order to reinterpret techniques and aesthetics, pushing back the boundaries of watchmaking and representing a perpetual source of fascination for collectors. Based on the latest research on the subject and published on the occasion of the 300th anniversary of the birth of Pierre Jaquet-Droz (1721-2021), this book offers a deep dive into the history of characters with a captivating journey. Born in La Chaux-de-Fonds, in what was then the principality of Neuchatel, Pierre Jaquet-Droz founded a watchmaking workshop and developed it through a combination of technical, artistic and commercial skills enabling it to reach international markets. His son Henry-Louis developed the family business and further diversified production, a significant portion of which found its way to China and its dignitaries, devotees of luxurious and ingenious mechanical marvels. This richly illustrated book aims to enable a rediscovery of their mechanical masterpieces as well as those of the Maison Jaquet Droz, whose rebirth and recent history are recounted here. These splendid historical and contemporary pieces embody a love of technical challenges and a taste for artistic refinement, adhering as much as possible to the sources of inspiration offered by nature. The Worlds of Jaquet Droz thus reveals part of the expansive universe of pre-industrial watchmaking while drawing parallels between past and present productions.

For all those who are interested in horology, whether as a hobby or within the trade, this user-friendly guide is invaluable as a wealth of information for the internal workings of clocks. Eric Smith provides a fully comprehensive manual to the repair of clocks, whether modern or antique. Lucid language accompanies practical diagrams and photographs to bring clarity to what is often a highly complex task. The author recognises the curiosity which many feel about the workings of clocks. It is for this reason that the author has written a guide which does not depict horology as too complex for those outside the trade, but rather as a fascinating and accessible occupation. The ten chapters go through the practical stages of how different clocks work and the tools and materials needed. Pendulum clocks, 30-hour, 8-day and 400-day clocks, chiming, striking, and electric and alarm clocks are all covered in detail. This new revised edition includes a chapter on working with more advanced tools including the lathe. The first chapter addresses the tools and materials which are required for repair, whilst the second chapter provides an explanation of the principles of clock mechanisms. The author subsequently takes the reader through specific aspects of clocks in each chapter, from the pendulums and balance wheels to cases and hands. A chapter on electric clocks gives advice on a significant sector of the clock market. In addition, this volume includes a glossary of terms, a bibliography and a list of suppliers of materials. It is also fully indexed. The author recognises that there is much in horology which cannot be self-taught from a book, yet Clocks and Clock Repairing is both a book to stimulate interest and a handy reference guide.

This is a richly imaginative study of machines for writing and reading at the end of the nineteenth century in America. Its aim is to explore writing and reading as culturally contingent experiences, and at the same time to broaden our view of the relationship between technology and textuality.
At the book's heart is the proposition that technologies of inscription are materialized theories of language. Whether they failed (like Thomas Edison's "electric pen") or succeeded (like typewriters), inscriptive technologies of the late nineteenth century were local, often competitive embodiments of the way people experienced writing and reading. Such a perspective cuts through the determinism of recent accounts while arguing for an interdisciplinary method for considering texts and textual production.
Starting with the cacophonous promotion of shorthand alphabets in postbellum America, the author investigates the assumptions--social, psychic, semiotic--that lie behind varying inscriptive practices. The "grooves" in the book's title are the delicate lines recorded and played by phonographs, and readers will find in these pages a surprising and complex genealogy of the phonograph, along with new readings of the history of the typewriter and of the earliest silent films. Modern categories of authorship, representation, and readerly consumption emerge here amid the un- or sub-literary interests of patent attorneys, would-be inventors, and record producers. Modern subjectivities emerge both in ongoing social constructions of literacy and in the unruly and seemingly unrelated practices of American spiritualism, "Coon" songs, and Rube Goldberg-type romanticism.
Just as digital networks and hypertext have today made us more aware of printed books as knowledge structures, the development and dissemination of the phonograph and typewriter coincided with a transformed awareness of oral and inscribed communication. It was an awareness at once influential in the development of consumer culture, literary and artistic experiences of modernity, and the disciplinary definition of the "human" sciences, such as linguistics, anthropology, and psychology. Recorded sound, typescripts, silent films, and other inscriptive media are memory devices, and in today's terms the author offers a critical theory of ROM and RAM for the century before computers.

Nanotechnology is the art, science, and engineering of designing materials, devices, and systems at the nanoscale from bottom-up and/or top-down approaches. The material properties at the nanoscale are governed by quantum mechanics, and hence are drastically different than those at the macro/micro scale. It is thus no surprise, that nanotechnology has led to a scientific and technological revolution. This book provides a gentle introduction to the field of nanotechnology for first-year undergraduate students. It not only covers the fundamental scientific concepts in a tutorial fashion, but also provides an overview of applications in nanoelectronics, spintronics, nanophotonics, nanofabrication and nanocharacterization. End of chapter research assignments focus on nanomanufacturing, computing and communication, renewable energy, defense applications, food processing and agriculture, automobile and aerospace technology, nanobiotechnology and bionanotechnology, industrial and consumer applications. Finally, the topics related to safety, health, and societal impact of nanotechnology are discussed.

'An utterly dazzling book, the best piece of history I have read for a long time' Jerry Brotton, author of A History of the World in Twelve Maps 'Not merely an horologist's delight, but an ingenious meditation on the nature and symbolism of time-keeping itself' Richard Holmes The measurement of time has always been essential to human civilization, from early Roman sundials to the advent of GPS. But while we have one eye on the time every day, are we aware of the power clocks have given governments, military leaders and business owners, and how they have shaped our lives and our world? In this spectacularly far-reaching book, David Rooney narrates a history of timekeeping and civilization in twelve concise chapters. Over their course, we meet the most epochal inventions in horological history, from medieval water clocks to Renaissance hourglasses, and from stock-exchange timestamps to satellites in Earth's orbit. We discover how clocks have helped people navigate the globe and build empires, but also, on occasion, taken us to the brink of destruction. This is the story of time, and the story of time is the story of us.

The public spaces and buildings of the United States are home to many thousands of timepieces--bells, time balls, and clock faces--that tower over urban streets, peek out from lobbies, and gleam in store windows. And in the streets and squares beneath them, men, women, and children wear wristwatches of all kinds. Americans have decorated their homes with clocks and included them in their poetry, sermons, stories, and songs. And as political instruments, social tools, and cultural symbols, these personal and public timekeepers have enjoyed a broad currency in art, life, and culture. In Marking Modern Times, Alexis McCrossen relates how the American preoccupation with time led people from across social classes to acquire watches and clocks. While noting the difficulties in regulating and synchronizing so many timepieces, McCrossen expands our understanding of the development of modern time discipline, delving into the ways we have standardized time and describing how timekeepers have served as political, social, and cultural tools in a society that doesn't merely value time but regards access to time as a natural-born right, a privilege of being an American.

Microsensors and MEMS (micro-electro-mechanical systems) are revolutionising the semiconductor industry. A microsystem or the so-called "system-on-a-chip" combines microelectronic circuitry with microsensors and microactuators.

Microsensors, MEMS and Smart Devices presents readers with the means to understand and evaluate microsystems. Advanced students and researchers in microelectronics, engineers and developers of microsensor systems will find this comprehensive treatment essential reading. Detailed coverage of material properties makes this an important reference work for mechnical engineers, physicists and material scientists working in the field.

The repair of clocks calls for a variety of skills and crafts, few of which can be 'picked up' by bench work alone. In the horological trade, it is technical practice that the 'prentice hand' is first tried out on clocks, before attempting repair work on watches. Clocks have the advantage of possessing sizeable and robust parts and of being easier to handle. But there the advantage for the repairer ends. The sizes, shapes, complications and even the nationalities of clocks appear to be without end. Every movement has detail difference and, naturally, the defects when due for repair, are as varied. In this book, the author has dealt with the usual faults likely to develop in each type of movement in general use; from the lordly grandfather to the humble alarm. All the tools and equipment are described and illustrated, together with the ways of using them. The craftsman's most important and valuable tools of all - his skilful fingers - are shown in use in the clearest manner. As is usual in N.A.G. Press textbooks, the drawings have been specially made from parts under working conditions. A glance through the book will show their usefulness and clarity. Over 400 line drawings are used throughout and the reader is left in no doubt of what he is asked to do in following the author's clearly written technical and practical instructions.

This book presents part of the iM3F 2021 proceedings from the mechatronics track.
